10.9.2 PM240-2 and PM240P-2 Power Modules: Current reduction as a function of the
installation altitude and ambient temperature
Current reduction as a function of the installation altitude and ambient temperature
At installation altitudes above 1000 m and temperatures higher than 40° C (low overload) or
50° C (high overload), the inverter output current is reduced. The following tables contain the
details.
